Hi,
I have 3 objective function namely F1, F2, F3. I used PSO for solving this function by combining 3 into 1 as follows.
F=a1*F1+a2*F2+a3*F3
a1, a2, a3 are some constants.
I want to plot all the 3 objectrtive function together to show the result.
Please help me in this.
Thanks in advance.

Hi,
You may find this example of Plotting 3-D Pareto Front helpful.
The example first shows how to obtain the plot using the built-in 'psplotparetof' plot function. Then solve the same problem and obtain the plot using 'gamultiobj', which requires slightly different option settings. The example shows how to obtain solution variables for a particular point in the Pareto plot. Then the example shows how to plot the points directly, without using a plot function, and shows how to plot an interpolated surface instead of Pareto points.

You used 'UseVectorized', true . When you do that, your function needs to return a 2D array that is (number of input rows) x (number of objective functions). However your code is returning only one row instead when a 2D array is input.
